Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and temperature grade. Ensure compatibility with the PSoC Designer development environment for configuration. Check for moisture sensitivity levels and reflow soldering requirements prior to assembly.

Application Specific Microcontrollers Selection Notes

Select this model when 16 kB of Flash and 2 kB of SRAM are required. Choose this part over the CY8C20336H variant if larger memory capacity is needed. Verify that the QFN package fits the PCB layout constraints. Confirm that the 24 MHz maximum clock speed meets the application's processing requirements.

Application Specific Microcontrollers Part Context

This component belongs to the CY8C20xx6A series of Programmable System-on-Chip (PSoC) devices. It shares architectural similarities with the CY8C20336H and CY8C20446H, differing primarily in memory size and package options. The series is designed to replace multiple traditional MCU components with a single programmable chip.
